“When Ibrahim al Qosi was released from Guantanamo Bay in 2012, a lawyer for the former Usama bin Laden aide said he looked forward to living a life of peace in his native Sudan.

Three years later, Qosi has emerged as a prominent voice of Al Qaeda in the Arabian Peninsula, appearing in a number of AQAP propaganda videos — including a 50-minute lecture calling for the takeover of Saudi Arabia.

The 56-year-old Qosi delivered a scathing critique of the Saudi monarchy — which appeared online on Feb. 6 — denouncing the Saudi government’s execution of more than 40 “mujahedeen” in January, according to the Long War Journal.

In the two-part lecture, titled “A Message to Our People in the Land of the Two Holy Mosques,” Qosi says the men were killed because they declared jihad against the “Crusaders” and opposition to American interests abroad.”
